Modern firewalls are becoming complex and anomalies may exist in their rule sets. Security log data, such as firewall logs and logs generated by intrusion detection systems, could provide useful information for the update and addition of existing firewall rule sets. In this paper, we focus on the development of an effective mechanism for firewall rule generation, and proposed an algorithm called Domain-Specific...
According to the analysis of intrusion detection model based on the Bayesian theory, an intrusion detection evaluation method was proposed. After comparison with the former related work and the analysis of the key evaluation target result, difference and quality between the performances of various intrusion detection systems were obvious. It can be proved that this performance evaluation is precise.
This paper proposed an intrusion detection system framework adapt to load characteristic under IPv6/4 environment; it uses decision-tree-based classification method, under guidance of a certain flow, creates dynamically rule matching tree adapt to load characteristic, reduces greatly the rule set that per packet or event need to be detected, improves the detection efficiency, can be utilized to solve...
